Diabetic & Hypertensive Retinopathy in Jaipur

Understanding Retinal Vascular Disorders

1. Diabetic Retinopathy (DR)

Persistently elevated blood glucose levels weaken the walls of tiny retinal capillaries, causing them to leak fluid, lipids, and blood into the retinal layers. In advanced stages, oxygen deprivation triggers the growth of abnormal, fragile new vessels (proliferative diabetic retinopathy) that can bleed into the vitreous gel or cause tractional retinal detachment.

• Non-Proliferative DR (NPDR): Early stage characterized by microaneurysms, dot-and-blot hemorrhages, and macular edema (swelling of central vision).
• Proliferative DR (PDR): Advanced stage with abnormal neovascularization, requiring urgent medical or laser intervention to prevent severe vision loss.
• Diabetic Macular Edema (DME): Fluid leakage at the center of the retina (macula), making reading, driving, and face recognition difficult.

2. Hypertensive Retinopathy

Chronic uncontrolled high blood pressure causes retinal arteries to thicken, stiffen, and narrow. Severe hypertensive episodes can result in retinal flame-shaped hemorrhages, cotton-wool spots (nerve fiber layer infarcts), and optic disc swelling (papilledema). Managing blood pressure in coordination with your physician is essential to prevent permanent retinal damage.

Modern Clinical Management & Care

• Comprehensive Dilated Funduscopy: High-magnification examination of the optic nerve and peripheral retina using 78D/90D non-contact lenses.
• Optical Coherence Tomography (OCT): Micron-level cross-sectional imaging to detect sub-clinical macular edema and monitor treatment response.
• Anti-VEGF Therapy: Targeted micro-injections to dry out retinal swelling and regress abnormal vessel proliferation.
• Retinal Laser Photocoagulation: Precision focal or pan-retinal photocoagulation (PRP) to seal leaking vessels and prevent vitreous hemorrhage.
